An electric train would head to Aurora more frequently than the once an hour schedule of today’s lumbering diesel train.

I reviewed Metropolitan Planning Council’s short and easy-to-read report about existing funding conditions of Chicagoland transit (CTA, Metra, and Pace) for Streetsblog Chicago. It was more eye-opening that I expected, mainly because I didn’t realize how poorly we fund transit here compared to cities nationwide and around the world.

The bit about only Atlanta spending less than Chicago when you compare our regions’ funding levels to what it was 20 years ago really caught some people’s attention.

The other part of the report, co-authored by Yonah Freemark who writes the blog The Transport Politic, that got some attention was the above map that showed how the Chicago region had more rapid (frequent) rail transit in 1950 than 2010. Lower mileage and funding over the past three decades meant fewer riders – that part is obvious and has been known to me, transit planners and managers. But this much? I had no idea.

My tweet about this map – to which Eric Fischer, Mapbox map designer and map historian responded with a map from one of the predecessor departments* of the current Chicago Department of Transportation – was retweeted ten times and clicked on over 100. That more than 70% of Chicagoland workers drive to work alone is not surprising given that our rapid transit network is built around rush hour service to downtown, where a minority of jobs are located.

* The department name on the map, published in 1939, is listed as Department of Subways and Traction, headed by commissioner Philip Harrington. This became the Department of Subways and Superhighways. The map shows two cross-Loop (east-west) subways linking Michigan Avenue businesses and intercity electric trains (that travel south, southeast, and near southwest) with the Union and Northwestern train stations (where people board trains to the west, northwest, north, and southwest).
